Below is a list of sites that I would think would be useful to the Linux newbie, put into two categories: Day to day Linux Sites, the sorta sites you may find yourself going back to tens or hundreds of times, and Linux Distribution Providers, this is a list of the 10 most well known Linux Distribution Providers, there are many more, but this will help you out, most (if not all) of the listed providers will allow you to download their distributions straight from their web site or ftp server. Have fun!
And Firstly: If you don't have Linux on your machine and you want to get started using the Linux shell, I offer free Linux Shells to people who have a valid reason for using one, It also gives you a small amount of webspace to place your own pages into. Why not visit the site and have a look around, and sign up if you wish!
